IMPROVEMENT IN GAS-CARBURETERS.

Specification forming part of Letters Patent No. 126,024, dated April23, 1872.

SPECIFICATION.

To all whom it may concern:

Be it known that I, GEORGE W. COLEMAN, of Kalamazoo, in the county ofKalamazoo and State of Michigan, have invented a new and usefulImprovementin Gas-Ua-rbureters; and I do hereby declare that thefollowing is a full and exact description of the same, reference beinghad to the accompanying drawing and tothe letters of reference markedthereon.

This invention relates to that class of carbureters which are pro videdwith a series ofpans located one over the other; and consists in certaindetails of construction by means of which a complete, simple, andeffective carbureter is obtained.

In the drawing, Figure l represents a vertical sectional elevation of myimproved carbureter; 'Fig. 2, a plan view; Fig. 3, a plan View of one ofthe pans reversed; and Fig. 4, a sectional elevation of one of the pans.

To enable others skilled in the art to make and use my invention I willnow proceed to describe fully its construction and manner of' operation.

The carbureter may be generally described as follows: It consists of anouter case ot any suitable material, inclosing a series ot' pans,located one over the other, the pans being surrounded with suitablefibrous material for taking up the gasoline, and with suitable openingsfor receiving and discharging the gas. The outer case is provided with asuitable supply-pipefor conveying the ait` to betreatedfrom a pump tothe carbureter, and with a suitable discharge-pipe for conveying awaythe carbureted air to any desired point. It is further provided with asuitable openin g for receiving the gasoline. The carburetor as a wholeis designed to be located beneath the surface of the ground at anyconvenient point. The main features just described are believed to becommon to this class of carbureters, and they do not form, therefore,the gist of this invention.

A represents the outer case, provided with the. air-supply pipe a,having a cock, al, gas pipe c2, and gasolinesupply pipe a3, as shown.Wit-hin the case is represented a series of pans, B B, of likeconstruction, arranged one above the other, and having suitable openingsto Aconneet the same. Each pan B is constructed as follows: b representsa rim, which may be circular in shape, or of other convenient form. b1represents the bottom plate, located above the horizontal center line ofthe rim, and provided with a tube, b2, which does not extend up to thetop of the rim, but terminates some distance below the upper edge of thelatter, as shown. .Below the bottom plate b1, and at right anglesthereto, is arranged a series otl transverse diaphragms or partitions,b3 b3, the members of which are attached to opposite sides of the rimalternately, and extend nearly across the plate, as shown. By means ofthis construction the spaces or passages between the diaphragms arecontinuously connected with each other. .The diaphragme b4 b4, next tothe rim, are provided with a transverse perforated partition, b5 b5, bymeans of which the triangular chambers m are formed, as shown. Withinthe continuous space formed between the diaphra gms bibs, andextendingfrom the perforated partition b5 upon one side to its fellowupon the other, suitable wicking is packed so as to entirely iill thesame, said wicking being secured in place by means of securing-strips116, as shown. It will be ob served that the wicking occupies thegreater part of the pan-that is, that the height of space which it fillsis much greater than that part of the pan above the bottom plate. The

transverse diaphragms are so arranged that l one of the chambers .r islocated beneath the tube b2, by which means a connection is made ,fromone pan to another through the tube, the

the bottom plate b1,with its chamber a', that communicates with thepassages about the diaphragm, over the tube b2 of the lower pan 5 and inthis manner the whole series is arranged.

The upper pan is provided with a cover, C, arranged below in a similarmanner to the lower portions of the pans proper, and provided withsuitable openin gs for discharging the carbuy.

reted air and receiving the gasoline. vWhen thus arranged gasoline ispoured into the cen tral supply-pipe a3 at the top of the case, asshown. As it enters the case it passes through the cover C into thefirst pan proper, which it fills until the top of the tube b2 isreached, when it runs over into the pan below, and from thence in asimilar manner, in succession, to the pans below.

When the bottom of the case is filled so that the top ofthe tube isreached, the gasoline overows into the pipe connecting with the air-pumpand discharges through a suitable cock proV vided for that purpose./Vhen the supply of gasoline reaches this point it is, of course, cutoi', as this is evidence that the carbureter is lled and ready foroperation. When operated, the air from the pump is forced through thebottom of the case into one'of the chambers .fr of the lower pan,through the perforated partition and thepassa-ges formed by thediapraghms b3 to the other chamber av, and from thence up through thetube into the next pan, and ina similar manner through the series.

It will be observed that the spaces between the bottom parts of the panare completely lled with wicking, (excepting the chambers w 06,) thelower portions of which (that is, all below the upper edge of the tubeb2) are sub* merged in the gasoline. It therefore follows that the airis forced through a nearly-continuous mass of wick-ing thoroughlysaturated with gasoline, and that, consequently, it/ is thoroughlyrcharged in a short space of time.

If desired, two or more tubes may be used to connect the pans with eachother.

By means of the construction described great compactness of form isobtained, as no portion of the carbureter is occupied by waste room.

The air is forced over the gasoline held in the air-tight spaces betweenthe pans through the mass of saturated wicking, by which means it isfinely divided and quickly carbureted.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

1. The pan B, constructed specifically as described, with the rim b1,bottom b located above the center of the rim b1, tube b2, transversediaphragms b3 b3 b4 b4, and perforated diaphragms b5, the spaces betweenthe diaphragms b3 b4 being completely filled with wicking and held bysecuring-strips b, as described.

2. The combination of the series of pans B, constructed as described,with the cover C, constructed as described, for the purpose set forth.

This specification signed and witnessed this 8th day of September, 1871.
